Hackathon organised in Nice for the ECODISTR-ICT data module

Oct 14, 2015

ECODISTR-ICT partners have organised a third hackathon in Nice. The core developers of the ECODISTR-ICT team had already organised a hackathon with a 3-day work session in April (Goteborg) and in May (Delft) to advance on ECODISTR-ICT IDSS prototype development.

Until that point, the CSTB was working from DIMOSIM module for energy calculation. The aim of this third session was to provide a data module operational for both the dashboard and external module. The GitHub4, had been used to gather and process feedback on the IDSS.

During this new session, partners started with a group of discussion on the specifications of the data connections and technical issues regarding the dashboard connections. Details are available on ECODISTR-ICT wiki.

Partners then worked on 4 main developments:

– A data module including a conversion from cityGML (storage format used in the ECODISTR-ICT platform) into geoJSON (dashboard format, format for encoding a variety of geographic data structures). The data module also filters exported data by: Level Of Details, Features type (roof, building, roads…) and Module properties (Energy ADE, traffic ADE, specific property required by the modules).

– A “C++ server/client with SSL security” technology on which the data module will be based. It is almost finished: the ECODISTR-ICT partners are close to a final solution and implementation.

– The definition of a module data sample based on the “cityGML Energy ADE” module to have a fully operational database for at least two simulations. The DIMOSIM module (CSTB) and LCA module (SP) will rely on this data format.

– The dashboard visualisation of geoJSON 2D cityGML.

This hackathon has been really prolific and positive for ECODISTR-ICT partners. The connection between the data module and the dashboard is operational for simple utilisation (e.g.: data collection from a single building). The conversion between module / data / dashboard is a work in progress that is expected to be finalized by the beginning of 2016. The data module to expert modules is at an alpha state and only needs an input on a completed file to be fully tested.

A first test will be made for the Valencia case study, which will be held by the end of October.
